| Question ID 13015 | Refer to the exhibit.
Which ds0-group option should you select to send automated number identification
information on outbound calls for this digital T1 voice circuit?
|
| Option A | e&m-fgd
|
| Option B | e&m-fgd
|
| Option C | fgd-eana
|
| Option D | e&m-delay-dial
|
| Option E | fgd-os
|
| Correct Answer | C |
Explanation Explanation: E&M signaling is often the preferred option for CAS because it avoids glare, it provides answer/disconnect supervision and it can receive Automatic Number Identification (ANI) with FGD and send ANI with FGD-EANA. In other words, you can have 1 channel-group for incoming calls and 1 channel-group for outgoing calls.
| Question ID 13016 | Refer to the exhibit.
The exhibit shows the Cisco IOS CLI output of debug ipdhcp packet, which was captured
on a router that is located at a branch office where a single IP phone is located. There is a
standalone Cisco Unified Communications Manager server at the central site, which also
provides DHCP services to the IP phone at the branch office. You are troubleshooting a
problem where the IP phone received an IP address in the correct subnet and with a
correct subnet mask from the DHCP server, but never completed registration with Cisco
Unified CM. Assuming the IP phone is correctly defined on Unified CM, which two
statements the network components are true? (Choose two.)
|
| Option A | The MAC address of the IP phone is 01ec44761e3e7d.
|
| Option B | The IP address of the DHCP server is 10.101.15.1.
|
| Option C | The MAC address of the VLAN 101 interface is 01ec44761e3e7d.
|
| Option D | The MAC address of the IP phone is ec44761e3e7d.
|
| Option E | There is no IP connectivity between the VLAN 101 interface of the branch router and the ip-helper address that is configured on this interface.
|
| Option F | Based on the information provided, we cannot conclude if there is IP connectivity between the IP phone and Cisco Unified CM.
|
| Correct Answer | D,F |
Explanation Explanation: In the logs the only information that we get is about the mac address of the IP phone because the IP phone is raising the boot request.
